ZFS: Quick Tips to Manage ZFS filesystem in Oracle Solaris 11

Oracle Solaris ZFS is the default root file system on Oracle Solaris 11. ZFS filesystem has integrated volume management, preserves the highest levels of data integrity and includes a wide variety of data services such as data deduplication, RAID and data encryption. Please find below quick tips to manage zfs filesystem in oracle solaris 11.

Create a ZFS pool with a single disk:

# zpool create testpool c3t2d0

Create a ZFS pool with 3 disks in RAID0 configuration:

# zpool create testpool c3t2d0 c3t3d0 c3t4d0

Create a ZFS pool with 3 disks in RAID1 configuration:

# zpool create testpool mirror c3t2d0 c3t3d0 c3t4d0

Create a ZFS pool with 3 disks in a RAIDZ configuration (single parity):

# zpool create testpool raidz c2t2d0 c3t3d0 c3t4d0

Create a ZFS pool with 1 disk and 1 disk as seperate ZIL (ZFS Intent Log):

# zpool create testpool c3t2d0 log c3t3d0

Create a ZFS pool with 1 disk and 1 disk as L2ARC (Level 2 storage cache):

# zpool create testpool c3t2d0 cache c3t3d0

Share a filesystem via NFS:

# zfs create zpool/fs1

# zfs set share=name=fs1,path=/rpool/fs1,prot=nfs rpool/fs1

# zfs set sharenfs=on rpool/fs1

Share a filesystem via CIFS:

# pkg install service/filesystem/smb

# svcadm enable -r smb/server

# echo “other password required pam_smb_passwd.so.1 nowarn”  >> /etc/pam.conf

# smbadm enable-user theitblogg

# zfs set share=name=sh1,path=/rpool/fs1,prot=smb rpool/fs1

# zfs set sharesmb=on rpool/fs1

Use shadow migration:

# pkg install shadow-migration

# svcadm enable shadowd

# zfs set readonly=on path/to/data # zfs create -o shadow=file:///path/to/data/target/new/path/to/data
